To a Zi whom 11mg; cmicem:

Be it known, that 1', OTTo J. :KL'HLKE, a citizen of the United Sintes,and a resident. of Akron, county of Summit, State of Clhio, haveinvented certain new and useful 11nnovenienl's in Vulcanizers, of whichthe following is :i specification,

This invention relates to vnlconizers, and 'whiie it is designedparticularly and especinllyi'or the vulcanization oi? endless elasticbands such as tire flops, the principles of the invention may beextended for other purposes and for wider utility.

The object of the invention is to construct a vulcanizer for the curingof trough-shaped rubber flops, the invention l'iaving to do with amechanism which will he quickly and easily operated and which willsatisfac' torily vulcanize the flops in a, short space of time andwithout loss of material. It is a further advantage of the invention cmthe flaps as cured in this apparatus require little if any trimming inorder to finish them, thus saving material and labor.

in the drawings and description there is shown one form of theinvention, it being understood mt changes and modifications may he madewithin the scope of the inveniion as set forth in the claims attachedhereto.

in the drawings:

Figure 1 is e side elevation of the improved vulcanizei', a portionbeing broken sway to show the interior construction;

Figure 2 is a front View with the volcanizcr in closed position;

Figure 3 is a plan View:

Figure 4i ise .i'ront view of the vulcanizer in open position;

Figure 5 is across-section on the line 5 of Figure 2;

Figure 6 is a cross-section on the line i" -6' of Figure 2.

The'vulcanizer of the present invention comprises a drum or form whichis provided with a circumferential trough or channel of the shape of theinner surface of the band of elastic material 01" tire flap. About thedrum is orrsngecl an expunsible jacket which is provided with mechanismby which the jacket is opened and closed and at the some time spoceclfrom the drum. The jacket is provided with e rih shaped to correspond tothe outer surface of the band and.

rious' elements of the device. At the center to enter within thechannel. The drum is provided with expansihle chambers or air begs whichexert pressure upon the material to shape it-properly and. the jacket isformed with a chamber adapted to receive-' steani for vulcanization,although other 60 heatingarrangements may be made. The

drum is rotatably end-slideibly mounted, as Wlll be explained, tofacilitate the placing of the uncured flap and the removal of thecompletely vulcanized flap from the machine v The mechanism herein showncomprises a,

base member 1- which is provided with the" vertical standard 2 whichsupports the/vaof the standard is nrrenged a bearing 3 in which issecured the horizontal shaft 4 which projects outwardly bey'ondthestandard end'slida-bly supports the freely rotumble drum or form 5,which is movable upon the shaft in the manner stated so as to permit theeasy insertion and removal of the flap. The drum is provided with anouter peripheral portion 6 which is formed with a central groove orchannel 7 of the: shape inletpipe 12 which passes through the C611"? I vtr ll shaft: 1. By connecting the bags flexibiy the air connections donot interfere with the free roiation orsliding of the drunnihe drumbeing shown in full lines in F igure" 1 in the curing position, thestripping.pos'i-; tion being shown in dotted. lines. In order to relieveany strain upon the pipeslO in the rotation of the drum, the coupling11, which isswiveled in the end of the shaft, carries a rod or closedpipe 41 which passes through a hole i2 in one of the drum spokes. Thisoperates eso (log "to turn the coupling with the drum. I

The'outer jacket 15 of the machine is ioo miiie to he jackets the flapis cured be tween the hue surface of the jackets and the air bags 1,reversal of the operations permit", the lemma; of the cured flap which ii be perfectly cured to shape,
